Spot button - The "Spot" light button is
visible if callsign spotting is enabled. Use this button to
toggle the callsign spotting reporter on and off. It
is automatically turned off when playback is selected in the Files
menu. The main window text is not searched if the viewer is
active, i.e., if it is displayed and the current modem is PSK.

RxID button - toggles the detection of
Reed
Solomon Identification codes.
TxID button - toggles the transmission of the RSID signal.
Tune
button - toggles the "Tune" mode which causes fldigi to insert a tone at
the current waterfall frequency. The peak-to-peak amplitude of
this tone is the standard by which you should
set your transmitter drive or adjust your antenna matching network.
The right most button is normally not visible. This is the
count-down timer button that is enabled when a macro button has been
configured to repeat after a specified number of seconds. This
button shows the count-down to the next transmission. Pressing
the button disables the count and restores fldigi to normal keyboard
operation.
